The scientific method of determining the age of the solar system
a. uses the detailed record of impacts on the moon to determine the age of the solar system.
b. shows that the age of the solar system is nearly 14 billion years.
c. uses the current surface temperature of the sun and the rate at which this temperature is decreasing.
d. uses measurements of the proportions of various isotopes in meteorites.

d. uses measurements of the proportions of various isotopes in meteorites.

Explanation:

The age of solar system is determined by using mostly meteorites and radioactive dating technique. Meteorites are components of our planets and By radioactive dating these meteorites allows us to give a estimated age of our solar system. The oldest meteorites which are found in the solar system are 4.571 billion years old, therefore the age of the solar system is 4.571 billion years.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
